What else can I help you with?
Are the alpha particle and helium nucleus the same thing?
Yes and no, alpha particles are a form or radiation (a helium nucleus), they are emitted from an unstable radioactive element which decays (and turns into some lighter element) by emitting the alpha particle. This form of decay is called alpha decay.
Which type of radioactive decay produces a helium atom?
Helium has two naturally occurring isotopes, 3He and 4He. Both are stable, so helium does not undergo decay in nature. Several synthetic isotopes exist. 5He is highly unstable and decays to 4He by emitting a neutron. 6He undergoes negative beta decay, producing 6Li. It has the longest half-life of any radioactive helium isotope, at 0.808 seconds. 7He is highly unstable and decays to 6He by emitting a neutron. 8He undergoes negative beta decay, followed immediately by emitting of a neutron, producing 7Li. Its half-life is 0.122 seconds. 9He is highly unstable and decays to 8He by emitting a neutron. 10He is highly unstable and decays to 9He by emitting a neutron.
Can you find a nucleus on its own in nature?
Yes, but you really don't want to. The only nucleus that can be found in nature is the alpha particle, emitting through nuclear decay. This is the nucleus of a helium atom and when it hits, you, it steals two electrons and ionizes your skin. This causes radiation burns.
Which is bigger a helium nucleus or helium proton?
The helium nucleus is larger than the proton. The He nucleus consists of two protons, and one (rarely) or two (most commonly) neutrons. (These are He-3 and He-4, respectively.) That would make the helium nucleus a multiple of three or four times the mass of that of a single proton.
What is an alpha particle equivilent to?
An alpha particle is equivalent to a helium-4 nucleus, or a helium-4 ion. A difference is that an alpha particle has a certain amount of energy associated with it, so it can said to be fast or hot. The energy is measured in thousands or millions of electron volts (keV or MeV).
Does helium have protons and neutrons in its nucleus?
Yes Helium has two protons and two electrons in its nucleus.
How many positive protons does helium have in its nucleus?
Helium has 2 positive protons in its nucleus.
What is a Nucleus of a helium atom?
The nucleus of a helium atom contains two protons and two neutrons.
How is the nucleus of hydrogen atom different from the nucleus of the helium atom?
The nucleus of hydrogen has 1 proton, whereas that of helium has 2 protons.
How is the nucleus of the hydrogen atom different from the nucleus helium atom?
The nucleus of hydrogen has 1 proton, whereas that of helium has 2 protons.
How is the nucleus of the hydrogen atom different from the nucleus of the helium atoms?
The hydrogen nucleus has a single proton. The helium nucleus has two protons and one or two neutrons.
What are you if you are gas with two protons in your nucleus?
If you are a gas with two protons in your nucleus, you are helium. Helium is a noble gas known for being lightweight and non-reactive.
